Distribution. Southern Canada, most of the USA, through Mexico to northern South America ( Fritzell and Haroldson 1982). Recorded habitats in Chihuahua are quebradas, sierras, valleys, and arid lands.

Remarks. This species is the most widely distributed canid in Chihuahua ( López-González and García-Mendoza 2012). It was the most frequently observed medium-sized and large mammal in the Rancho Experimental Teseachi.
